Same questions on those foreign/ghost devices here:
I vote for a “do not automatically add devices to the integration” system option. Not having entities enabled is one (already good) thing, but the list of devices still explodes. Other platforms like OpenMQTTGateway (OMG) can even disable auto discovery for the ESP itself, right from HA. I miss that for my ESPHome based Bluetooth Proxy a lot - which would also block iBeacon Tracker collecting devices like crazy.
